To all whom t may concern: A

lie it known that 1, An'rrrnrr el.. Tiener, a subject of the King of Great Britain, and a resident of the city ot New York, orough of Brooklyn, in y,the county of Kings and State of New York, have invented a new and improved Electric-Lamp Switch,

of which the tollowing'is a tull, clear, and

exact description.

My invention has for its object to provide an electric lamp switch which may be disposed within a porcelainv candle ture of the ordinary construction and which may be operated tromJan end ot the said porcelain candle tixture.

@ther objects of the invention are to provide convenientmeans :tor operating the switch which will not impair the attractiveness of 'the fixture.

Additional objects of the invention will appear in the following specification in which the preferredtorm ot my invention is described. i

1n the drawings similar characters ot reference refer to similar parts in all the views, in which- Figure 1 is a sectional View of a porcelain candle lixture, the switch being disposed within the porcelain candle; Fig. 2 is a sectional view on the line 2'-2 of Fig. 1; Fig. 3 isA a sectional view yshowing one ol the operating disks; Fig. 4t is a sectional view showing the other operating disk; Fig. is a transverse sectional View showing the relationship of the two disks; and Fig. 6 is a sectional view showing another operating means for the switch.

lly referring to the drawings, it will be seen that the lamp wires 19 and -11 are dis posed in a tube 12 and thatto this tube 12 there is secured by a set screw 13 a disk 14E on which is disposed the porcelain candle 15` this porcelain candle 15 being ot the usual construction?. l/Vithin this ,porcelain candle the lamp switch 16 is disposed, Mounted on the tube 12 there is a cap 17 and on this cap 17 there is disposed an insulating member 18, two conducting stand between the said standards 19 there is an insulating ratchet member 21, a conducting member-22 being mounted on the insulating ratchet member 21 and being in electrical engagement with one of the conducting standards 19, this conducting member 22 vhaving portions 23 disposed over the alternate teeth ot the insulating ratchet member 21, so that when the insulating ratchet member 21 is rotated the spring contact member 2t will intermittently contact with the portions 23 of the conducting member 22. 'lhe resilient vcontact member 24 is mounted on the standard 25 which is supported by and extends upwardly from. the insulating member 18. Supported by the conducting standards 19 and 25 there is an insulating member 26, 'to the top ot which there is secured a socket 30, the conducting standard 25' being in electrical communication with the contact 28 at the center of the socket 27 by means of a conducting plate 29.

ing standards 19 and is mounted on a horizontal axis. Members 33 and 3d which are mounted in bearings in the conducting Vstandards 19 serve to hold the insulating lheld yieldingly with its shoulder 38 disposed against the stop 39 by means ot a spring d@ passed around the member 31 having its terminal 41 secured to the plate 37 and its terminal 42 secured to the standard 19 adjacent the member 311. lt will therefore be seen that when the plate 37 is rotated it will by`-means ot the ratchet plate 36 rotate the ratchet plate 35 and with it the insulating member 21 to move the teeth of the ratchet member 21 relatively to the spring contact member 24. A normal rotary movement 'of the ratchet member 21 will' bring the resilient contact member 241 ico against the periphery .of the ratchet meml portions of the conducting member 22 disposed thereover it will be understood that/ when the resilient contact member 24 coines in contact with the periphery of alternate teeth of the ratchet member 21 the circuit will be, closed between the conducting standard 19 Vadjacent the conducting member 22 and the conducting standard 25. A

flexible member 43 ofany suitable'character is secured to the plate 37, preferably in a channel 44, and this flexible member 43 is led down .through an opening 45 in the insulating member 18 and through an opening 46lin the cap 17, the flexible member 43 being then disposed through an orifice 47 in the disk 14.

Disposed below 'the disk 14 for rotating relatively-thereto on the tube l2 there is a disk 48 which has an annular channel 49 in whichthere are ribs 50. The terminal of the flexible member 43 isfenlarge'd as shown at 51 and this enlarged terminal is disposed t in the channel 49 to be engaged by one of the ribs 50. When the terminal 5l is thus engaged by onel of the ribs 50 and the disk -48 is rotated by means of a collar 52 to which it is secured, the terminall 51 will be rotated until it reaches one of the recesses 53 in the disk 14, when the terminal 51 will enter the said recess 53 thereby permitting the rib 50 to pass. When the rib 50 Vpasses the enlarged terminal 51 of the iexible member .43 the flexible member 43 i with its terminal 51 will move back'to normal position as shown in Fig. 1 of the drawings, the spring 40 servin to rotate the plate 37 vto bring the parts ack to the said position.

In the modified form of the invention shown in Fig. 6 of the drawings, the poi-,

l celain candle fixture 15a is mounted dil Patent.

Vso

rectly on a base collar 54 which has an opening 55 near its lower end through whiclithe fiexible member 43 is disposed,

saidlexible. member 43 having an enlarged terminal 51a which maybe drawn down by the user to operate the switch which has been described in this specification.A
